Title: Measuring Process for Measuring Chargeable Electrical Consumption from an Electrical Network and Electronic Electricity Meter
Inventor: ALVARENGA LANDULFO MOSQUEIRA
IPC: G01R21/133
Filed: 1995-01-11
Abstract: A process is described for the measurement of electricity consumption, that is specially suitable for small consumers, comprising the steps of continuously measuring consumer current, integrating said current with time to obtain a value (A.h) relating to consumption; adjusting the integration in function of the voltage of the network to obtain an adjusted value (Av.h) proportional to a preestablished unit of electricity consumption; and computing the number of preestablished units obtained to provide a value proportional to chargeable electricity consumption. Preferably, the adjustment to the integration is carried out in accordance with four bands of network voltage, in the form of a nominal band on either side of the nominal network voltage, an overvoltage band, an extended voltage band below the nominal band an an undervoltage band.  An electricity meter without any power source is also described, comprising a current transformer (TC) having the consumer load line (15) as primary and a secondary generating a current representative of the current in the load line, a circuit connected to the secondary to integrate the value of such current with time, detector means for detecting when the integration circuit reaches a preestablished chargeable unit value of consumption of electricity and counter means associated with the detector means to sum ?he detected units of consumption.  A housing is also described which is a single part and of extremely simple manufacture.

Patent CA-2203579-A1 (CA)
Title: Self-drilling stud
Inventor: JANUSZ MICHAEL
IPC: E04C5/06
Filed: 1997-04-24
Abstract: A self-drilling stud particularly suited for use in normal weight or lightweight composite deck system where the use of standard weld studs is inappropriate because of the relatively thin material cross-section of the steel support member. The stud is heat treated to a dual-hardness level so that a portion of the stud is capable of drilling the support member and the decking.      The remaining portion of the stud remains relatively ductile so that it can withstand and transfer shear loads imposed by shifting of the concrete slab which overlies the decking to the main support members. The stud is a single piece fastener which includes specially formed annular flanges which enhance interlocking between the stud, the concrete slab and support members.
Patent CA-2204429-A1 (CA)
Inventor: DINSMORE JONATHAN
IPC: A61K35/30
Filed: 1995-11-07
Abstract: Porcine striatal cells and methods for using the cells to treat neurological deficits due to neurodegeneration are described. The porcine striatal cells can be modified to be suitable for transplantation into a xenogeneic subject, such as a human. For example, the porcine striatal cells can be modified such that an antigen (e.g., an MHC class I antigen) on the cell surface which is capable of stimulating an immune response against the cell in a xenogeneic subject is altered (e.g., by contact with an anti-MHC class I antibody, or a fragment or derivative thereof) to inhibit rejection of the cell when introduced into the subject. In one embodiment, the porcine striatal cells are obtained from a pig which is essentially free from organisms or substances which are capable of transmitting infection or disease to the recipient subject. The porcine striatal cells of the present invention can be used to treat neurological deficits due to neurodegeneration in the brain of a xenogeneic subject (e.g., a human with epilepsy, head trauma, stroke, amyotrophic lateral sclerosis, Parkinson's disease, Alzheimer's disease, or Huntington's disease) by introducing the cells into the brain of the subject.
